; To (LZZ whom it mct y concern:

- Be it known that we, BnAnBURr HILL,

- improve the construction of copy-holders and to provide a simple, inexpensive, and efficient book copy-holder or marker designed to be applied to largebooks to enable accurate copies and extracts to be made from the same and capable of being quickly engaged'with and removed from a boo A further object of the invention is to provide a device of this character having an ada justableindicating device adapted to be varied in length to suit the size of a book and capable of conforming readily to the curvature of the rounded or bulged portions of the leaves of a book.

- Another object of the invention is to pro-.

-vide a copy-holder having book engaging or clamping devices and adjustable and detachable indicating means capable of being readily arranged to fit a book and adapted to be uickly separated from the book engaging or c ampin means to permit the leaves of a book to e-freely turned.

With these andother objects in view the invention consists in the construction and.

novel combination and arran ement of parts hereinafter fully described, ustrated in the accompanyingdrawings, and pointed out in the claims hereto appended, it being under.- stood that various changes in the form, proportion, size, and minor details of construction within the scope of the claims maybe ing one end of the rod and illustrating the manner of clamping the same. Fig. 5 is a detail perspective view of the slide.

Like numerals of, reference designate corresponding parts in all the figures of the drawmgs.

1 designates a centrally-arranged rodforming a guide for the indicating means and arranged at the center of a book 2 when the "same is open, as illustrated in Fig. 1 of the drawings. The rod is held by a pair of clamps 3, arranged at the top and bottom of the book and connected with the "same by the means hereinafter described. Although itis preferable to 'employ a pair of clamps, as

illustrated in the accompanying drawinrgls, y

yet the device may be provided with 0 one clam ,and the same may be arranged either at' t e top or bottom of the book. Each v of the rod-supporting clamps consists of a pair of corrugate or crimped jaws 4, forming a plurality of rod receiving seats and extending upward from the book when the same is in a horizontal or inclined position and adapted to permit the rod to be adjusted to suit the thickness of the book to which the device is applied. The upper or outer. ends -5 of the jaws are bent outward to rovide a flaring mouth or entrance to enab e the rod to be readily introduced intothe jaws, and

the said rod may be quickly placed between the jaws and instantly removed therefrom to permit the leaves of the book to be turned. The lower ends 6 of the jaws, which are resilient, are bent outwardly and are secured to a rod or bar 7, which connects a pair of bookengaging clips 8. The jaws are engaged at their outer portions by a pair of springs -9, constructed of resilient metal and havin lower or inner outturned ends 10, arrange on the'inner or lower ends 6 of the jaws and secured to the connecting-bar 7 by fastening devices 11. The fastening devices also pierce the lower or inner end 6 of the jaws and secure the sameto the connecting bar or rod 7. The connecting bar or piece 7 consists of a thin strip of steel or other suitable material, and the clips 8, which are arranged. at the ends of the connecting bar or piece and which are adapted to engage the covers ofthe book,

are substantially U-shaped and consist of upper straight flat aws 12- andlogimer'jaws 13, terminating short of theoutergjends of the aws 12 and having their terminalsslightly curved. The upper flatjaws. are ldapted to fit against the inner faces of the covers to afsame against a book, said indicating-strip or ford a firm support for the rod-engaging clamp. One end of the rod is reduced at 14 for engaging the adjacent clamp, and the reduction of the rod provides opposite shoulders which fit against the opposite edges of the jaws for holding the rod against longitudinal movement therein. The other clamp is designed to engage the rod at different points, whereby the device is readily adjustable to suit the size of a book. The rod receives an adjustable slide 15, consisting of a I rectangular loop composed of front and back walls and top and bottom connecting walls or portions, the front and back walls being connected with circular a ertures 16 to receive the rod. The slide,w ich is open at o posite sides, receives a pair of extensib e strips or members 17 and a spring 18. The strips or members which form the indicator or marker are constructed of thin resilient material and are adapted to lie against the opposite pages of a book, as indicated in Fig. 1 of the drawings. They are extensible and are adapted to be drawn outward to arrange themto suit the size of the book 'to which the device is applied. The spring 18, which is provided with angularly-disposed sides, is provided with a central bend 19, forming a groove or seat for the rod. The angularly-disposed sides of the spring extend laterally of the slide and engage and hold the markers or indicating-strips against the book. The spring holds the slide in its adjustment, and it also retains the extensible indicatingstrips or markers in their adjustment. The

slide, with its indicating-strips or markers, is

adapted to be moved along the rod, as required, and the indicating-strips or markers will enable the contents of a book to be accurately copied.

The device is especially adapted for copying records from lar e books, and the bookengaging means whic carry the rod-supporting clamps are adapted to be quickly applied to a book. The rod which forms the guide for the indicating means may be quickly arranged in the clamps and instantly removed therefrom when it is desired to turn the leaves of a book, and the adjustable indicating-strips or markers may be readily drawn outward and moved inward to arrange them to suit the size of a book. The seats of the clamps permit the rod to be readily adjusted to suit the thickness of a book.

Having thus fully described our invention,

what we claim as new, and desire to secure by Letters Patent, is

1. A device of the class described provided with an indicator having a'thin indicatingstrip or marker constructed of resilient material and adapted to be flexed to conform to the configuration of a book when the same bulges at the center, and a spring engaging the indicating-strip or marker for holding the marker being adjustable independently of the spring for varying its length and being retained in its adjustment by the said spring.

2. A device of the class described, co1npris ing a guide arranged to lie along the center of a book, and indicating means provided with a thin indicating member or marker constructed of resilient material and slidably connected at an intermediate point with and movable across the said guide and extending from opposite sides of the same for engaging both of the leaves of a book.

3.
